What is the difference between mobile phone memory and system space?

The subject is different. System space: refers to the system memory, which is the main area of the system to temporarily store program instructions and data.Internal storage space: refers to flash memory, which is a form of electronic clearable programmatic read-only memory.

Another general sense of mobile phone system memory is the built-in memory (usually referred to as "memory") used to store things, that is, the body memory. The Android mobile phone system occupies part, and other installers also occupy a part. At present, the storage space of mobile phones is generally 8GB, 16GB or 32GB.

The storage space manufacturer of the mobile phone will be divided into two parts. One is the system space, that is, the system of your mobile phone itself, including the storage place of the software you install by default in the future.

- In the macOS system, press Command+spacebar to open Spotlight search. Enter "sysctl -a", and then press Enter. Find the "hw.mem" column in the output results, which shows the memory size of your computer.

COMS memory is a chip that can store data with very little power. Due to its extremely low energy consumption, CMOS memory can be powered by a small battery integrated into the motherboard, which can also automatically charge when the computer is powered on.

In addition, the requirements of the operating system also need to be considered. The memory requirements of different operating systems will also be different. For example, the Windows operating system is inIn the case of 2GB of memory, there may be a problem of slow operation, while some lightweight Linux distributions may consume relatively less memory.
